SPECIFICATION forming part of Letters Patent No.629,1'73', dated July18, 1899. Application filed March 4, 1899. Serial No. 707,763. (Nomodel.)

To all whom, it may concern: Beit known that I,-WILLrAn-REESE, a citizenof the United States, residing at Carnegie,

in the county of Allegheny and State of Penn-'1 Sylvania, have inventedor discovered a new and useful Improvement in Car-Couplers, of which thefollowing is a full, clear, and exact description, referencebein g hadto the accom-v panyin g drawings, forming part of this speci- Io cation,in which- Figure 1 is a central longitudinal vertical section through adraw-head furnished with my improved variable-position locking-pin, thejaw being shown in section.' Fig. 2 is a cross-sectional View taken onthe line 11 l1 of Fig. 1. operation of coupling on a curve.

Fig. 3 is applan view showing the showing the tail of the locking-jawlocked at Fig. 5 is a detail view coming into. contact with thelocking-pin. Fig. 6 is a detail view in front elevation, partly insection, of the locking-pin, showing z 5 thetail of the jaw inengagement with the main pin, .the supplemental portion being raised.Figa-7 is a detail view ofl the supplemental sliding portion. 4

My invention relates to the class of Atwin- 3o jaw couplers conformingLto `the Master Car- Builders standard, and has reference moreparticularly to the mechanism Aemployed in locking and unlocking thetail of the swinging jaw, the construction. otherwise involving 3 5 nochange from the well-known type of J anney couplers.

Referring'to the drawings, 2 is the drawhead, in which is pivoted theusual swinging jaw or knuckle 3, provided with the extended 4o tailpiece4, made with a vertical iiat face 5 on the inner side of its end andhaving its outer end rounded at 6 and tapered down to a rounded nose. l

The interior of the draw-head is hollow and -provided with a verticalslot 7 8 in the upper 5o extending'portion 1l is correspondinglynarrowed in width.

Fig. 4 is a plan View of one draw-head, partly in section,

ASlidinglyrmounted upon thebolt at the oppositeside from the approachot'the swingi'ngtailpiece is a supplemental bolt 12, vertically movablewith relation to thernain bolt and adapted to be held upwardly by thetail ofthe jaw when the backward mot-ion of the jaw is purposelyarrested at such point immediately under the supplemental bolt, therebypermitting the main bolt to drop downwardly in front of the tailpiece toarrest its forward movement, but holding the jaw in a partiallyclosedposition. y The object of such construcv tion is to better, adapt thecoupler to use on curves, where, as shown in Fig. 3, the part-s willmove readily and easily come into contact and accomplish the act ofcoupling if the jaw is partially opened. The supplemental bolt Al2projects upwardly andhas a sliding bearing in therecessed head of themain bolt and is Valso provided Vwith a'vertical slot 13, intowhichprojects a pin 14, mounted in the main bolt, which pin limits thedownward travel of the supplemental bolt. It will be noticed that thecorner or face of the supplemental bolt is slightly beveled onv theapproach side, so that in the operation of entirely closing the jaw incoupling the tailpiece will ride under both the beveledportion 10 andthe bottom of the supplemental bolt, causing both to rise thereby,although it will'be seen that the supple-V Inental bolt will be carried'up with the main bolt by reason of the pin lll.

In operation the tail of, the lookin g-j aw will 'ordinarily swingaround, raising the main and supplemental bolts and seating itself in aclosed position back of both bolts, as shown in Fig. 4:. When it isdesired to set it as de- Y scribed, the head is thrown around until thetail passes beyond the beveled portion 10 o f the main bol'twhen suchbolt will fall by gravity and the tail .will arrest the fallof thesupplemental bolt, as in Fig. 6, and will bear Vagainst the inner faceof the main bolt until thrown back to the last position in the act ofcoupling. Raising of both bolts is accomplished in the usual manner, theslot and pin preventing excessive downwardtravel of the supplementalbolt.

It will be noticed that a spring 15 is provided, attached to theinterior of the drawhead and bearing upon the tail of the lockingl IOOjaw in such a manner as to throw it outwardly when the end of the tailis released, thus automatically opening the jaw.

I-Iaving described my invention, what I claim isl. In a car-coupling,the combination of a draw-head, a swinging jaw pivotally mounted thereinhaving an extended tailpiece rounded at its outer end, a mainlocking-bolt vertically and slidingly mounted in the draw-head in thepath of the swinging tailpiece'provided with a beveled shoulder, areduced lower eX- tension and a recessed head, and a supplementalindependent vertically-movable bolt mounted on the side of the mainlocking-bolt, projecting upwardly into the recessed head of the mainlocking-bolt and provided with a beveled shoulder and means for limitingits downward movement.

2. In a car-coupling, the combination of a draw-head, a swinging jawpivotally mounted therein having an extended tailpiece rounded at itsouter end, a main locking-bolt vertically and slidiugly mounted in thedraw-head in the path of the swinging tailpiece provided with a beveledshoulder, a reduced lower extension, a limiting-pin and a recessed head,and a supplemental independent verticallymovable bolt mounted on theside of the main locking-bolt havinga vertical slot in engagement withthe limiting-pin, a beveled lower shoulder adapted to be engaged by thetailpiece, and an upper extremity projecting into the Arecessed head ofthe main bolt.

3. In a car-coupling, the combination of a therein having an extendedtail piece rounded at its outer end, a spring mounted in the draw-headand adapted to bear against the tailpiece when closed, a mainlocking-bolt vertieally and slidingly mounted in the drawhead in thepath of .theswinging tailpiece provided with a beveled shoulder, areduced lowerext-ension, a limiting-pin and a recessed head, and asupplementalindependent vertically-movable bolt mounted on the side ofthe mainr locking-bolt having a vertical slot in engagement with thelimiting-pin, a beveled lower shoulder adapted to be engaged by thetailpiece, and an upper extremity projecting into the recessed head ofthe main bolt.

4e In a car-coupling, in combination with a drawhead, and a swinging jawpivotally mounted therein having an extended tailpiece rounded at itsouter en'd: the locking-bolt consisting of the main bolt 9 having abeveled shoulder 1'0, a downward extension 11, a recessed head at theupper end with means for attaching a lifting device and a limitingpinlll, with the supplemental bolt l2 beveled on its lower approach sideand having a sliding bearing in the recessed head of the main bolt, avertical slot 13 for engagement with pin 14, and adapted to operateindependently of the main bolt or to be lifted with it.

In testimony whereof I have hereunto set my hand.
